According to the Office for National Statistics composite price index, today's prices in 2020 are 7,104.07% higher than average prices since 1934. The British pound experienced an average inflation rate of 5.10% per year during this period, meaning the real value of a pound decreased.

In other words, £100 in 1934 is equivalent in purchasing power to about £7,204.07 in 2020, a difference of £7,104.07 over 86 years.

The 1934 inflation rate was 0.00%. The current inflation rate (2019 to 2020) is now 1.50%^{1}. If this number holds, £100 today will be equivalent in buying power to £101.50 next year.

This chart shows a calculation of buying power equivalence for £100 in 1934 (price index tracking began in 1750).

For example, if you started with £100, you would need to end with £7,204.07 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When £100 is equivalent to £7,204.07 over time, that means that the "real value" of a single U.K. pound decreases over time. In other words, a pound will pay for fewer items at the store.

This effect explains how inflation erodes the value of a pound over time. By calculating the value in 1934 dollars, the chart below shows how £100 buys less over the past 86 years.

According to the Office for National Statistics, each of these GBP amounts below is equal in terms of what it could buy at the time:

Then plug in historical CPI values. The U.K. CPI was 15.8 in the year 1934 and 1138.2433607545 in 2020:

£100 in 1934 has the same "purchasing power" or "buying power" as £7,204.07 in 2020.

To get the total inflation rate for the 86 years between 1934 and 2020, we use the following formula:

CPI in 2020 - CPI in 1934CPI in 1934

Plugging in the values to this equation, we get:

Politics and news often influence economic performance. Here's what was happening at the time:

- American and Canadian prairies suffer during "The Great Dustbowl", a period of drought and severe dust storms.
- John Dillinger becomes commonly known as America's first Public Enemy Number One.
- Hitler brutally purges the leadership of the Nazi party in an event known as "Night of Long Knives".
- The Assassination of Leningrad mayor Sergey Kirov is used as a pretext by Stalin to start the Great Purge of the Communist party.

Raw data for these calculations comes from the composite price index published by the UK Office for National Statistics (ONS). A composite index is created by combining price data from several different published sources, both official and unofficial. The Consumer Price Index, normally used to compute inflation, has only been tracked since 1988. All inflation calculations after 1988 use the Office for National Statistics' Consumer Price Index, except for 2017, which is based on The Bank of England's forecast.
